Type only the first 10 to 15 letters of the business name. If you do not find the license, type the business name again with 1 or 2 fewer characters.

Commas and periods are not used in the business name, but apostrophes are. For example: Al's Builders.

Spaces between initials matter. If the name has initials in it, type the initials first with a space between them, and then type the initials without a space between them. For example: "A B Smith Builders" and then "AB Smith Builders"
